I had a C6 Z06 and sold it only because it was impractical at the time I owned it. Simple fact is the M3 feels extremely slow compared to it, as the Z06 is faster in EVERY performance category all while getting better gas mileage. The Z06 was speed that never wore off, no matter how often you opened it up. The kool-aid drinkers here will say the interior sucks because that's what they read, but I wouldn't say our M3's interior is exactly cutting edge.

I had my Z06 and M3 at the same time. No comparison when it comes to performance. The M3 was very nice and I would buy another, but the Z06 is a crazy mofo. I loved it!
